74LVX273MTCX

Overview

The 74LVX273MTCX is an octal D-type flip-flop with a positive-edge clock and asynchronous active-low reset, manufactured by onsemi (formerly Fairchild). It operates within a supply voltage range of 2 V to 3.6 V, featuring single-ended inputs and outputs in a non-inverting configuration. The device provides 8 mA low-level output current and -4 mA high-level output current, with a maximum propagation delay of 20 ns at nominal supply. It is housed in a 20-lead TSSOP package suitable for surface mount applications.

Feature Summary

• Octal D-type flip-flop architecture with positive-edge triggering
• Asynchronous active-low reset functionality
• Single-ended input and output configurations
• Non-inverting logic polarity

Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose memory storage elements
• Buffering and latching digital signals

Procurement Notes

Verify the manufacturer designation carefully, as the component was originally from Fairchild Semiconductor and is now produced by onsemi. Confirm the specific ordering suffix matches the required tape-and-reel packaging format. Ensure the part number corresponds to the LVX series specifications rather than other similar logic families.

Selection Notes

Select this component when designing systems requiring an octal storage element with low-voltage operation between 2 V and 3.6 V. It is appropriate for applications needing asynchronous reset control and moderate speed performance with a 20 ns propagation delay. Consider the TSSOP-20 package constraints for PCB layout and thermal management.

Part Context

This device belongs to the 74LVX273 series, which represents low-voltage CMOS logic technology. The series is characterized by compatibility with standard 5 V environments while operating at lower voltages. The 273 designation specifically indicates an octal D-type flip-flop with reset, widely used in general-purpose digital logic designs.

Replacement Considerations

The part number alias 74LVX273MTCX_NL may be available as a direct substitute. Verify pinout compatibility and electrical parameters before replacing. Cross-reference with other manufacturers offering equivalent LVX series octal flip-flops in TSSOP-20 packages.
